Adaptive Control of Tubular Chemical Reactor

In this paper the simulation results of the adaptive control inside the tubular chemical reactor with counter-current cooling in the jacket is shown. The adaptive controller is based on the choice of the External Linear Model as a linear representation of the originally nonlinear system parameters of which are identified recursively. The polynomial method together with spectral factorization and pole-placement method satisfies the basic control requirements. The controller could be tuned via position of the closed-loop root. Although the system has strongly nonlinear behaviour the proposed controller provides good control results.
